Hydrogen iodide, HI, decomposes at moderate temperatures according to the equation 2HI(9) - H2 (g) + L (g) The amount ofI, in the reaction mixture can be determined from the intensity of the violet color of I,; the more intense the color, the more I, in the reaction vessel. When 3.91 mol HI was placed in a 5.00-L vessel at a certain temperature, the equilibrium mixture was found to contain 0.431 mol I2. What is the value ofK, for the decomposition of HI at this temperature? K. =

At a certain temperature, the equilibrium constant, Kc,Kc, for this reaction is 53.3. H2(g)+I2(g)−⇀↽−2HI(g)Kc=53.3 At this temperature, 0.800 mol H2 and 0.800 mol I2 were placed in a 1.00 L container to react. What concentration of HIHI is present at equilibrium?

An equilibrium mixture of PC1, (g), PC1, (g), and Cl₂ (g) has partial pressures of 217.0 Torr, 13.2 Torr, and 13.2 Torr, respectively. A quantity of Cl₂ (g) is injected into the mixture, and the total pressure jumps to 263.0 Torr at the moment of mixing. The system then re-equilibrates. The chemical equation for this reaction is PC1₂(g) + Cl₂(g) = PCl, (g) Calculate the new partial pressures, P, after equilibrium is reestablished. PPCL, Pch PPCL, = = = Torr Torr Torr
